Definitions
- the longitudinal deformation curves of the decks are substantially symmetrical with respect to the plane of separation of the decks so that the maximum distance between the decks is located near the middle of the thrust points (drive members and fixed supports) and represents twice the maximum deformation of each deck.
- each displacement member is located at the opening of the slots, so as to allow precise movement of the free ends of the upper walls of said slots.
- control assembly comprises:
- control assembly further comprises measurement means to obtain information on the effective curvature of the free upper part of the lower deck and the programmed curvature.
- FIG. 2 represents a view in vertical section along the line II— II of FIG. 1, and
- the working edges of these two upper and lower aprons respectively carry a folding punch P and a corresponding matrix M.
- the bending angle of a metal sheet or sheet depends on the extent of the penetration of the punch P inside the die
- the lower apron 2 comprises an upper part 22 and a lower part 21 situated respectively above and below the two slots 3a and 3b.
- the lower part 21 of the lower deck 2 is fixed at its ends to the flanges 9a and 9b forming the frame of the press brake.
- the lower part 21 can be fixed by welding or any other means.
- the upper part 22 of the lower deck 2 is in turn only connected to the lower part 21 by means of the central zone located between the two bottoms of said slots 3a and 3b.
- These hydraulic cylinders 6a and 6b are arranged at the opening of the slots so as to allow precise movement of the free ends of the upper walls 31a and 31b of said slots 3a and 3b, as will be described in detail later.
- These hydraulic cylinders work in retraction, which allows a bringing together of the upper walls 31a and 31b respectively towards the lower walls 32a and 32b whereby the deformation curvature of the free upper part 22 of said lower apron 2 is modified before any operation folding, i.e. before the vertical movement of the upper deck 1.
- control assembly 13 comprises measurement means 7a and 7b arranged at the openings of the two slots 3a and 3b. These measurement means have the function of measuring the distance between the free end of the upper part 22 and the end fixed of the lower part 21 of the lower apron 2, in order to control the deformation curvature of the lower apron 2.
